First airborne gravity results over the Thwaites Glacier catchment, West Antarctica [PDF]

Geochemistry, Geophysics, Geosystems, 2008
Recent satellite observations of Thwaites Glacier in the Amundsen Sea Embayment, West Antarctica, have shown that the glacier is changing rapidly. The causes of its dynamic behavior are uncertain but are of concern because this glacier has the most ...

Large-Scale Atmospheric Drivers of Snowfall on Thwaites Glacier

2020
<p>High snowfall events on Thwaites Glacier are a key influencer of its ice mass change. In this study, we diagnose the mechanisms for orographic precipitation on Thwaites Glacier by analyzing the atmospheric conditions that lead to high snowfall events.

Turbulence Observations in the Grounding Zone Region of Thwaites Glacier

2020
<p>Antarctic ice shelves restrain the flow of grounded ice into the ocean, and are thus an important control on Antarctica’s contribution to global sea level rise. West Antarctica represents the largest source of uncertainty in future sea level projections, and Thwaites Glacier has the potential to influence sea ...

Peter Davis of the British Antarctic survey on changes in the Thwaites Glacier

Bulletin of the Atomic Scientists, 2020
On the Thwaites Glacier on Antarctica’s western shelf, researchers are going all-out to learn what is happening deep under the surface of the ice, out of sight: How much is melting from below, wher...

Safety Bands of Thwaites Glacier

Mass loss from the Antarctic Ice Sheet is the main source of uncertainty in projections of future sea-level rise. These uncertainties essentially stem from the fact that some regions, such as Thwaites Glacier, may reach a tipping point, defined as irreversible mass loss on human time scales, with a warming climate.

Future irreversible loss of Thwaites Glacier relative to global warming

2023
The speed of West Antarctic melting is a very important factor in determining the degree of future global sea level rise. Loss of the Thwaites glacier due to global warming will have various regime changes in line with changes in the Earth system.

Simulating 3D calving dynamics at Thwaites Glacier

Recent advances in the Elmer/Ice modelling suite have allowed 3D simulation of unrestricted calving geometries at tidewater glaciers such as Jakobshavn Isbrae. We present the first use of this model in an Antarctic setting. The more stochastic nature of calving at Antarctic ice sheets when compared to a Greenlandic setting has discouraged the ...
